HYDROOARBON-MOTOR.

Specification of Iietters Patent.

Application filed September 10, 1917. Serial No. 190,604.

To all whom it may concern:

Be it known that I, WALTER E. BLAINE, a citizen of the United States, and residing at Detroit, lVayne county, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the following is a specification.

This invention relates to hydrocarbon motors and more particularly to means for cleaning the air supplied to the motor.

The principal ob ects of the invention are to provide a device which will efficiently remove the matter in suspension from the air and yet not be cumbersome or too large for attachment to the motor of a vehicle; to provide a device which is of such small dimensions that it can be located close tothe motor and carbureter and wholly within the bonnet of the motor vehicle covering the engine; to provide a device which has no moving parts and consequently requires no attentlon; to provide a simple means for collecting the matter separated from the air; to provide a means for regulating the air pressure in the float chamber of the carbureter in accordance with the air pressure in the cleaning device; to provide a device which is adapted for connection to all the air inlets of the motor carburetor; and to provide an air cleaning (lGVlCB'WhlCll ofl'ers no resistance to the flow of air therethrough and consequently does not afi'ect the efliciency of the motor. Other objects and features of the invention will be apparent from the description taken in connection with the drawings, in which:

Figure 1 is a plan view of a portion of a motor vehicle showing the bonnet with a part broken away to disclose the motor and the air cleaning attachment as applied to the motor; s

Fig. 2 is an elevation of the parts shown in Fi 1;

Fig. 3 is a sectional elevation through the cleaning device taken. substantially on the line 33 of Fig. 1, the upper portion ofthe coil being broken away;

motor vehicle, part of which is broken away in order to show the engine and the arrangement of the air cleaning device. The englne B may be provided with a carbureter U 01 any desired type and has connected thereto the air cleaning device D, which is located under the bonnet.

As shown in the drawings, the air cleaning device comprises a coil of pipe 10 having an inlet end 11 and a'discharge end 12. The form of carbureter shown in the drawings has a main air inlet 13and an auxiliary air inlet 14. The outlet 12 of the air cleaning device is adapted to be connected with the main air inlet by means of the conduit'15 and the device is also provided with an outlet 16 which is, adapted for connection with the auxiliary air inlet 14:. Thus as the motor operates, air is drawn in through the air cleaning inlet 11 and supplied to the main required. In passing through the air cleaning attachment, the air travels in a helical. path and therefore has given to it a whirling motion which causes matter in suspension to be thrown outward. In order to remove and collect this matter the turns of the coil of pipe are each formed with similarly arranged apertures 17 which register with corresponding apertures 1.8 in the cover 19 of a receptacle 20. The coil of pipe may be secured to this cover by means of the lugs 21 and bolts'22. As shown in Fig. 8, the receptacle may bep'artia'lly filled with a liquid, preferably an oil, and between adjacent apertures 18 is a partition 23 which is attached to the cover by means such as bolts 24, the partitions extending downwardly and projecting into the liquid so that' a series of compartments is formed between thepartitions and thecover and top surface of the liquid. Thus each turn of the coil of pipe has a connection through the aperture 17 with one of these compartments, and as the compartments are separated air cannot pass out through an aperture 17, of one turnof the coil, and back through an aperture of another turn. As shown in Figs. 1 and 2, the inlet 11 of the device may be connected with a stove 25 by means of a conduit 26, the stove being provided to heat the air supplied to the motor so that a better vaporization of the motive fluid will be obtained.

In the operation of the device the air supplied to the motor is drawn through the stove 25, thus heating it and carrying it to the inlet 11 of the cleaning attachment. In passing through the device D the air travels in \a helical path and is given a whirling motion which throws the matter in suspension to the outer Wall of the coil, whereupon it passes through the aperture 17. and into the receptacle 20. Thus the matter in sus pension in the air supplied to the motor is removed and collected. In order to equalize the air pressure in the float chamber 27 of the carbureter and the cleaning attachment, a pipe 28 is arranged to connectthe .last turn of the coil and the float chamber of the carbureter. Thus if the air pressure on the intake side of the carbureter is reduced, the pressure inthe float chamber will be brought to the same amount because of the connection 28, and consequently an amount of motive fluid in proportion to the amount of air fed will be forced through the inlet valve of the carbureter. It will be obvious that if the connection 28 were not provided, too much motive fluid would be forced through the needle valve at times when the pressure on the inlet side of the carbureter was reduced.

- In designing the cleaning attachment according to this invention, the cross sectional area of the turns in the coil of pipe should be such that the air passing through the coil will have sufficient velocity to generate a centrifugal force which will cause the matter in suspension to be thrown outward. On the other hand, the size of the coil is not so small that any substantial resistance will be offered to the flow of the air therethrough.

From the foregoing it will be apparent that the means for separatin matter in suspension from the air supplier to the motor is exceedingly simple, has no moving parts and therefore requires practically no attention. Furthermore, the attachment is small and it may be located beside the engine and under the usual bonnet of the motor vehicle.

Although aspecific arrangement and type of device hasbeen described, it is apparent that the form and details thereof may be varied to a considerable extent without departin from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination with the carbureter of a hydrocarbon engine having a float chamber, of means for separating the matter in suspension from the air supplied to the carbureter, and means for maintaining the air pressure in the float chamber substantially the same as in said separating means.

2. The combination with the carburetor of a hydrocarbon engine having a float chamber, of means for separating the mat ter in suspension from the air supplied to the carburetor and a pressure-equalizing pipe connecting the float chamber and said separating means.

3. A hydrocarbon motor attachment for cleaning the air supplied to the motor comprising a coil of pipe, a plurality of the turns of the coil each having an aperture through the wall thereof, a receptacle secured to the coil having corresponding apertures. and a partition in the receptacle between adjacent apertures.

4:. A hydrocarbon motor attachment for cleaning the air supplied to the motor comprising a coil of pipe, a plurality of the turns of the coil each having an aperture through the wall thereof, a dust collecting receptacle arranged to receive the matter discharged through said apertures and means forming a separate compartment in the receptacle for each aperture.

5; A hydrocarbon motor attachment for cleaning the air supplied to the motor comprising a coil of pipe having an inlet at one end and two outlets at the other, a receptacle secured to said coil, each turn of the coil having an aperture communicating with the interior of the receptacle and means includinga-liquid forming a separate compartment' for each aperture.

6. A hydrocarbon motor attachment for cleaning the air supplied to the motor comprising a coil of pipe the adjacent turns of which are in contact with each other and of uniform cross sectional area, a receptacle disp'osed below said coil and secured thereto, said coil having apertures communicating with the interior of the receptacle and means within the receptacle forming a separate compartment. for each aperture.
